So I picked up this great (what looks to be a) Yamaha bass drum (possibly a Rydeen?) and it has the Pearl copy tom mounting hardware for L-arms that are the same diameter as the Pearl stuff.

Well, I need to replace the base that's screwed onto the bass drum as that one is lacking parts. I've included pictures of it here with a ruler next to it so you can tell scale, but will a Pearl tom mount base fit these holes? Is it a direct match? I'm assuming so, but I no one has one in stock for me to check, so perhaps one of you here can check out your Pearl kit and let me know if it's a direct match. Then I'll just replace this one with one made by Pearl.
